By royal appointment. Stephanie Beacham is a Princess Undone

She was the glamorous one, the royal sister occasionally touched by scandal who captivated everyone she met. Princess Margaret, the most glamorous figure of her generation, has a final chance to be of service in Richard Stirling’s new play A Princess Undone which tours this autumn.

A Princess Undone is set in Kensington Palace in 1993. While the Royal Family is at Balmoral, Margaret removes several bags of correspondence from the Queen Mother’s home, including potentially sensational letters from Prince Charles – and Diana, Princess of Wales. She means to burn them all. But there are other papers.

Some of them relate to Margaret herself, and a scandal as dangerous as anything since. When an ex-gangster arrives to bring her even closer to her past, the Queen’s sister has the choice to make or break her family yet again.

Inspired by actual events, A Princess Undone has its premiere at Cambridge Arts Theatre on October 19 and it sheds light on one of the Royal Family’s most controversial, enigmatic members.

Witty, charming and provocative, yet ultimately on her own, Princess Margaret is not easily forgotten.

Stephanie Beacham, internationally famous and acclaimed for her work on television (The Colbys, Dynasty, Bad Girls), film and stage, returns to the theatre to create a role as iconic as any she has played before.

Directed by Matthew Gould it also stars Jason Merrells (Emmerdale, Waterloo Road, currently starring in Alan Aykbourn’s How the Other Half Loves in the West End) as ex-gangster John Bindon.
